Hokule'a, The Hawaiian Canoe Traveling The World By A Map Of The Stars
"She sails by the memory of the stars.
Her bones are lashed together with 6 miles of rope. Her twin wooden masts are lowered and outstretched only by the power of muscled arms. And once fully extended, the red, V-shaped sails announce who she is. She is the Hokule'a, Hawaii's famous voyaging canoe, built in the double-hulled style used by Polynesian navigators thousands of years ago to cross the Pacific. Now, she's on a journey to make history, traversing the globe by wayfinding — an ancient Polynesian skill that requires memorizing hundreds of stars and where they rise and set on the ocean horizon. She has already crossed 26,000 miles of ocean and still has a year left to go." http://www.npr.org/sections/codeswit...p-of-the-stars |

Of course you come from a community of celestial sphere unfortunates and refuse to acknowledge that the 24 hour system and the Lat/Long system are built around the Earth's geometry and rotation within the framework of the calendar system. Until accurate and practical watches were developed by John Harrison the only way was to 'sail the parallels' of latitude using the height of Polaris above the horizon,something Columbus would have done. I have dealt with the assault on timekeeping and astronomy when the late 17th century dummies tried to model the Earth's motions using RA/Dec and that awful conclusion that shames everyone who looks at it in silence - http://hypertextbook.com/facts/1999/JennyChen.shtml |

An astronomical hypothesis was generally accounting for motions of various celestial objects and particularly the planets and the moon and before that the Sun in geocentric astronomy.

Now, the exact time of the day at the place where we are, can be ascertained by well known and easy observations of the Sun if visible for a few minutes at any time from his being ten degrees high until within an hour of noon, or from an hour after noon until he is only 10 degrees high in the afternoon; if therefore, at any time when such observation is made, a Timekeeper tells us at the same moment what o'clock it is at the place we sailed from, our Longitude is clearly discovered." John Harrison The key feature is how to exploit the 'average' 24 hour day and convert that average into constant rotation at a rate of 4 minutes per degree of rotation but that means starting back in antiquity with the creation of the calendar framework. I offered you the opportunity to develop software that uses the annual motion of the stars minus circumpolar motion as this long term observation will produce imaging of the planets and moon as they actually move through space and outside their motion from horizon to horizon each night . |

Their coats shed somewhat during the year, but are known to shed profusely twice a year. You're welcome |

A stone-age culture's product. What would the Phoenicians, Greeks, Vikings, Spanish, Portuguese, English have all done without the benefit of a Hawaiian canoe to sail the seas? |

You're welcome I have no need to criticize you Rolando as you are caught up in the cogs of a clockwork driven nightmare and have yet to let the light shine in on an unthinking mind - "And twofold Always. May God us keep From Single vision & Newtons sleep" William Blake For people destined to navigate in space they will have to set aside the rotating celestial sphere and begin to look at motions as they really do happen seen from a moving Earth so what I do sometimes is take a slight detour in taking into account Earth-bound timekeeping,its roots and its misuse by those careless people a few centuries ago. |

It's certainly true that I wouldn't want to try putting his first attempt at a Naval chronometer on my wrist, as it was about twice the size of a breadbox. Of course, before there were wris****ches, there were pocket watches; that history usually goes back to the Nuremberg Egg - but the earliest watches were not very accurate, and thus wholly unsuitable for use as chronometers.
